“…Several GRE algorithms have addressed the issue of generating locative expressions (Dale and Haddock 1991;Horacek 1997;Gardent 2002;Krahmer and Theune 2002;Figure 26 Interpreting the blue ball near the red ball. Varges 2004). However, all these algorithms assume the GRE component has access to a predefined scene model that defines all the spatial relations between all the entities in the scene.…”

This article describes the application of computational models of spatial prepositions to visually situated dialog systems. In these dialogs, spatial prepositions are important because people often use them to refer to entities in the visual context of a dialog. We first describe a generic architecture for a visually situated dialog system and highlight the interactions between the spatial cognition module, which provides the interface to the models of prepositional semantics, and the other components in the architecture. Following this, we present two new computational models of topological and projective spatial prepositions. The main novelty within these models is the fact that they account for the contextual effect which other distractor objects in a visual scene can have on the region described by a given preposition. We next present psycholinguistic tests evaluating our approach to distractor interference on prepositional semantics, and illustrate how these models are used for both interpretation and generation of prepositional expressions.

This paper presents an approach to incrementally generating locative expressions. It addresses the issue of combinatorial explosion inherent in the construction of relational context models by: (a) contextually defining the set of objects in the context that may function as a landmark, and (b) sequencing the order in which spatial relations are considered using a cognitively motivated hierarchy of relations, and visual and discourse salience.

“…NP generation for query constraints can be seen as a form of referring expression generation (see Dale and Reiter 1995, for example). In contrast to Varges (2004), the phrases produced by the chart generator are not directly associated with their extension (the set of objects they denote) since these are held in the database backend rather than in-memory.…”

Interactive question answering and constraint relaxation in spoken dialogue systems

We explore the relationship between question answering and constraint relaxation in spoken dialogue systems and develop dialogue strategies for selecting and presenting information succinctly. In particular, we describe methods for dealing with the results of database queries in information-seeking dialogues. Our goal is to structure the dialogue in such a way that the user is neither overwhelmed with information nor left uncertain as to how to refine the query further. We present two sets of evaluation results for a restaurant selection task: one is a system performance evaluation experiment involving twenty subjects, the other is an experimental evaluation of the use of suggestions involving sixteen subjects.
